Garhwali is a hilly dialect originated from medieval Hindi. In the middle period of the course of
development of Hindi, there were many "apbhransh" (dialects) of
Hindi. Of these, the most popular "apbhransh" of western India was
"Saurseni". Saurseni gave birth
to three sub-language those were Western-Hindi (in the region
around Mathura, Meerut and Delhi), Rajasthani (in Rajasthan) and Pahari (west-sub
Himalayan region).

Garhwali is a dialect spoken by four million Garhwali people,
mostly living in the Garhwali region of a north Indian state
Uttarakhand. Almost all people who can speak and understand
Garhwali can speak and understand Hindi also. This is one of the
dialects which is shrinking very rapidly and becoming out of
fashion. Most of the educated people who live in cities hardly
speak Garhwali and in most cases parents still speak and understand
Garhwali but their children cannot. Although it is easy to write
Garhwali in Hindi (Devnagri) script, there is hardly any literature
available in Garhwali.

In the last few decades there have been many singers like Narendra
Singh Negi who have made people interested in Garhwali by their
popular songs and videos. On an average there is one movie in four
or five years in Garhwali. If you are planning to visit tourist
places of this Middle Himalayan Region (Badrinath, Kedarnath,
Uttarkashi, Joshimath etc.), your knowledge of Garhwali can be
useful.
